What could go wrong with GST Reg

Address proof mismatch

Business address on your electricity bill must match the application exactly - even flat number format matters.
Mismatch triggers an officer query that adds 3-5 days.
Ollvy CA cross-checks every address document before filing.

Aadhaar OTP fails

GST registration requires Aadhaar OTP on your linked mobile number.
If the number is old or inactive, OTP fails and you cannot proceed - must be fixed at an Aadhaar centre first.
Ollvy verifies your Aadhaar-linked mobile before filing.

Operating without registration

If turnover crossed Rs. 40 lakh (goods) or Rs. 20 lakh (services) without registration, you owe 100% of unpaid GST plus Rs. 10,000 minimum penalty.
Penalty starts from the date you should have registered, not when you get caught.

Frequently asked questions about GST Registration

When is GST registration required?

Mandatory above Rs. 40 lakh turnover for goods, Rs. 20 lakh for services (Rs. 10 lakh in NE/special category states). Required for any interstate sale regardless of turnover, and for all e-commerce sellers.
